Mundorf MCoil BL BL71 0.47 mH inductor
BL71

BL71-0,47

MCoil VL71 is our resin-soaked air coil – completely free of core-related effects and fully linear. It is ideal for midrange, treble, and correction branches because the resin soaking reduces Macro-Microphony, thereby audibly improving clarity, contour, and fine dynamics.

Technologies

Baked Varnish / Resin Soaked

Fixes the windings to form a stable unit. Vibrations are effectively damped.

Air Core

Air coils are the uncompromising reference: maximally linear, without distortions caused by the core.

OFC Copper

Characterized by a purity of at least 99.995% copper

Tight Tolerances

Make sure that the left and right channels work identically, important for stable stage and positioning.

Our services for manufacturers and cooperation partners

We manufacture coils in-house. This gives us flexibility—from material selection and micro-series production to standard products.

Consulting

Material & design

Which coil material and design are best suited for your application? We provide independent advice, regardless of whether you ultimately choose a standard product or a custom solution.

Implementation

Your material and parameter mix

Do you have a specific vision for the material, winding type, and electrical parameters? We can implement combinations outside of our standard range—either using our modular system or through a new development.

Production

Custom small and micro-series

Thanks to our in-house production, we can manufacture coils in very small quantities—starting from a batch size of 1, provided it is economically viable. We can also provide approval samples before full-scale production upon request.
